National Instruments 777318-425 Relay Output Module for Compact FieldPoint

Part Number 777318-425 is the identifying part number for the National Instruments cFP-RLY-425 Relay Output Module for Compact FieldPoint. It is suitable for deterministic LabVIEW Real-Time applications as it offers highly reliable and powerful standalone embedded execution of advanced floating-point algorithms. The 777318-425 features 8 SPST, non-latching-type relay channels that sit on the normally open mode by default. The maximum switching capacity for resistive load is as follows: 3 A at 250 VAC, 5 A at 150 VAC, 5 A at 0 to 18 VDC, and 0.2 A at 125 VDC. The maximum switching power on each channel is 750 VA, 90 W whereas the maximum switching load is 1 mA at 5 VDC. The maximum current through all channels is 200 Amp-squared. 

The expected mechanical relay life for the 777318-425 is 2 & 10^7 operations whereas the electrical life is as follows: 1.5 × 10^5 operations at 5 A, 30 VDC, and 3 A, 120 VAC, and 3 × 10^4 operations at 5 A, 250 VAC. The relay operate time is <10 ms while the relay release time is <7 ms. The contact bounce time is <1 ms while the contact material in the relay is gold-plated silver alloy. The 777318-425 features green POWER and READY indicators and weighs 7.1 oz. Likewise, it draws a power of 1.45 W from the network module at the operating temperature range. The channel-to-ground and channel-to-channel isolation is 250 Vrms (continuous) and resides under Measurement Category II. 

The recommended temperature range for the operation of the 777318-425 is -40 °C to 70 °C at a relative humidity of up to 10% to 85% RH. Likewise, the device is only meant to be used within a maximum altitude of 2000m. Note that the device is only meant to be indoors or they have to be mounted inside a sealed enclosure for outdoor use. On the other hand, it can be stored at -55 to 85 °C. The device meets the following safety standards for electrical equipment for measurement, control, and laboratory use: IEC 61010-1, EN-61010-1, UL 61010-1, and CAN/CSA-C22.2 No. 61010-1.
